Endodontic Management of Fused Teeth: A Case Presentation

Fusion is a rare developmental anomaly that is described as a union of two independently developing primary or secondary teeth. It can be either partial or complete, depending on the developmental stage of the teeth when the union occurs, and is infrequently seen in the permanent posterior dentition. Endodontic therapy of these teeth requires special care and careful management because of their abnormal anatomy. This paper reports a case of fusion between a maxillary lateral incisor and a supernumerary tooth and describes the endodontic and restorative management applied.
